Vizio TV question and groups

I have created a group so one button turns it all on at the same time… Here’s the group

lv_tv:
  name: LV TV
  entities:
    - media_player.vizio_smartcast
    - switch.living_room_ambient_tv
    - light.tv_stand
    - media_player.shield

Everything comes except the TV itself…

If I run just a button for the tv like this …

- <<: *cb_standard_button_narrow
          name: TV 
          icon:  mdi:television-classic
          entity: media_player.vizio_smartcast 

The TV turns on and off just fine… so why isn’t it working in the group, any ideas?

Thank you all!
